Given trapezoid WXYZ, what is XY?

stepan [7]

Answer:

XY = 16 ft

Step-by-step explanation:

The mid segment DE is half the sum of the parallel bases, that is

$\frac{XY+WZ}{2}$ = 20 ( multiply both sides by 2 to clear the fraction )

XY + WZ = 40

XY + $\frac{3}{2}$ XY = 40 ( multiply through by 2 to clear the fraction )

2XY + 3XY = 80

5XY = 80 ( divide both sides by 5 )

XY = 16

NEED HELP ASAP!Noah and Lin are each trying to solve the equation x^2-6x+10=0. They know that the solutions to x^2=-1 are i and

suter [353]

Let's solve your equation step-by-step.

x2−6x+10=0

For this equation: a=1, b=-6, c=10

1x2+−6x+10=0

Step 1: Use quadratic formula with a=1, b=-6, c=10.

$x= -b$ ± $\sqrt{\frac{b^2 -4ac}{2a}$

x = −(−6)± $\sqrt{\frac{(-6)^2 -4(1)(10)}{2(1)}$

x= 6± $\frac{\sqrt{-4} } {2}$

x = 6± $(\sqrt{4})( \sqrt{-1} )$ / 2

x = 6 ± $(\sqrt{4})( i )$ / 2

$(\sqrt{4}) = 2$

6 ± 2i / 2 = 3 ± i
